Gene Sweeney Jr., Baltimore Sun

The Red Sox rotation is something of a question mark heading into the season, with several arms that could exceed expectations or disappoint. Lefty Jon Lester (above) returns as the staff ace after a rough 2012, and he'll be joined by RHP Clay Buchholz, RHP Ryan Dempster, RHP John Lackey and LHP Felix Doubront.
